Notes[]

  • The stat reduction that can be applied during combat by Pulse Smog is considered a temporary debuff.
  • The "Special cooldown charge -X" effect will stack with the "Special cooldown charge +X" effect.
    • For example, if a unit is affected by both  Guard and  Special Cooldown Charge +1, the effects will stack and the cooldown will go down without penalty or bonus.
  • If used alongside another source of "Special cooldown charge -X", only the higher of the two charge reductions will apply.
    • This means that if a unit has two "Special cooldown charge -1" effects from two different sources, the battle will play out as if only one "Special cooldown charge -1" effect is active.
  • Skills such as  Tempo Echo and  Arcane Þrima will neutralize effects that inflict "Special cooldown charge -X" on its user.
  • Pulse Smog's Special cooldown count increase that occurs during combat is a flat +1 and is not affected by effects related to Special cooldown charge such as  Guard,  Special Cooldown Charge +1, and  Tempo Echo.
    • All flat cooldown count increases and/or reductions during combat will stack with each other if they trigger at the same time.
      • For example, if a unit has  Preempt Pulse and  Hush Spectrum, the effects will stack and the unit's cooldown count will neither increase nor decrease.
  • The stat decrease that can be applied by Pulse Smog is considered a  Penalty.
    • Any 【Penalty】 effect on a unit lasts until that unit takes an action. If the unit takes multiple actions in a turn, they will only have  Penalties for their first action.
      • If the unit also has  Grand Strategy, any  Penalties will remain active until the start of that unit's next phase.
  • Pulse Smog applies the  Guard status effect.
    • Any 【Penalty】 effect on a unit lasts until that unit takes an action. If the unit takes multiple actions in a turn, they will only have  Guard for their first action.
    • The "Special cooldown charge -X" effect will stack with the "Special cooldown charge +X" effect.
      • For example, if a unit is affected by both  Guard and  Special Cooldown Charge +1, the effects will stack and the cooldown will go down without penalty or bonus.
    • If used alongside another source of "Special cooldown charge -X", only the higher of the two charge reductions will apply.
      • This means that if a unit has two "Special cooldown charge -1" effects from two different sources, the battle will play out as if only one "Special cooldown charge -1" effect is active.
    • Skills such as  Tempo Echo and  Arcane Þrima will neutralize effects that inflict "Special cooldown charge -X" on its user.
  • Pulse Smog triggers before after combat Specials such as  Galeforce and Røkkr AoE Specials.
  • Cooldown count changes from effects that activate at the same time as Pulse Smog (after combat) are not considered in Pulse Smog's conditions. Effects such as  Special Spiral 4,  Prof's Guidance, and  Pulse Smog will have their effects stack.
